Suzuki–Miyaura cross-coupling of activated alkenyl tosylates is described. The results not only represent the first examples of the rhodium-catalyzed Suzuki–Miyaura coupling of activated alkenyl tosylates with arylboronic acids under mild conditions, but also provide an efficient route for the synthesis of some natural product-like compounds, such as furan-2(5H)-one, coumarin, pyrone, and quinolin-2(1H)-one
描述了一种有用且有效的铑催化剂体系 - [RhCl(PPh3)3/DPPF] - 用于活化甲苯磺酸烯基酯的 Suzuki-Miyaura 交叉偶联。该结果不仅代表了在温和条件下活化的甲苯磺酸烯基与芳基硼酸在铑催化下 Suzuki-Miyaura 偶联的第一个例子,而且还为合成一些天然产物类化合物(如呋喃-2)提供了有效途径。 (5H)-one、香豆素、吡喃酮和喹啉-2(1H)-one 衍生物。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
